Title: Method for joining ceramics
Inventor: NISHIKAWA TETSUYA
IPC: B23K1/19
Filed: 1991-04-23
Abstract: PURPOSE:To simplify the joining stage by brazing ceramics in which the faces to be joined are metallized by an Mo-Mn method in a hydrogen atmosphere having a specified dew point or in an atmosphere of a nitrogen-hydrogen mixed gas by copper. CONSTITUTION:The joined faces of an alumina ceramics rod, e.g. contg. 92% Al2O3 are coated with mixed metallic powder constituted of, by weight, 80% Mo and 20% Mn, which is burned at 1450 deg.C for 30min in a nitrogen-hydrogen atmosphere having 30 deg.C dew point to metallize the surfaces of the ceramics. Next, a pure copper plate is put between each other of the above metallized faces, which is heated at 1150 deg.C for 20min in a hydrogen atmosphere having 0 to 10 deg.C dew point or in an atmosphere of a nitrogen-hydrogen mixed gas, and brazing is executed. In this way, ceramics/ceramics or ceramics/metal can be joined without the need of improving the wettability by a brazing filler metal by applying plating to the Mo-Mn metallized faces.

Abstract: PURPOSE:To obtain an image with proper density even from an original with high transmissivity by correcting the output of a photodetecting means according to the output signal of a light transmissivity detecting means, and adjusting density data from a copy body. CONSTITUTION:When copying operation is started, a lamp 10 is turned on to make a scan for the density and size detection of an original and while a transmissivity detection sensor 21 detects the transmissivity of the original 6, an original detection sensor 8 detects the image density and size. When the original 6 is thick, the original detection sensor 8 outputs its detection signal and the transmissivity detection sensor 21 outputs the low-wave-height signal; when the original 6 is thick, the high-wave-height signal is outputted. A correcting circuit 13 corrects the output signal of the sensor 8 on the basis of the output signal of the sensor 12 and supplies a corrected signal to a control circuit 12. Consequently, proper density data for making an automatic density adjustment so that the quantity of light supplied to a photosensitive body is proper is obtained and an image of high quality is formed.
